Jeg tror nærmere at det er "Elektro/ Kemisk" forbundet... I anførselstegn for ikke helt at være i stand til at forsvare min tese!
- Men jeg ser det ikke forbundet til
skummer producent, men rettere som at være en naturlig reaktion imellem lige og til tider ulige. Eller en skubbet ballance i kemien som drager til hinanden, eller ikke.
Der tiltrækkes, eller frastødes. Og det gælder groft i alle livets forhold (!), og det ses i særdeleshed hvad angår
kemi som det at holde saltvand; især at gøre sig gældende med elementer som betingelse for optag eller ikke...

Solubility of Calcium Carbonate in Marine Aquaria
There are several interesting results of the supersaturation of calcium carbonate in our tanks. One that many people quickly encounter in maintaining a reef tank is that heaters and other warm objects (e.g., pump impellers) seem to become coated with solids over time. Why is this?
This solid is principally calcium carbonate, though it likely has other ions in the crystal as well (magnesium and other metals, phosphate and other anions, etc.). The two reasons that this happens are readily understood, but the primary one is not at all obvious.
One contribution to the reason that calcium carbonate precipitates on heaters is simply that calcium carbonate in seawater is slightly less soluble as the temperature rises. Since calcium carbonate is already supersaturated, the effect is that when the water is warmed, the supersaturation of calcium carbonate rises, making precipitation more likely.
